Biologists believe that a large number of species that are part of the rain forest ecosystem are on the verge of extinction. Which statement BEST describes the role of urbanization in this disaster?
A) Urbanization leads to deforestation and loss of habitat for many species.
B) Many animals are captured or killed by poachers, significantly reducing their numbers.
C) Viral epidemics that break out in human populations spread to animals in the ecosystem.
D) Factories cause a significant rise in temperature in the forests, endangering many species.

Urbanization is the main reason for the exploitation of the rain forests which has lead to the extinction of species used to be residing in the forests ecosystems. Following are the factors which are responsible for such disaster with the expension of urbanization:

1. Infrastructure: The land is the main requirement which is responsible for the exploitation of rain forests. The large area is required for the accommodation of the large human population, construction of roads, highways and bridges. This has replaced many habit-ant animals from their native land and also leads to extinction due to ecological disturbance.

2. Increasing needs of food, herbs and wood: Many species of wooden trees could be found in the rain forests which have now extincted due to increasing demand for wood. The herbs have been wiped up for the preparation of medicines and drugs. The large number of tree populations are also exploited due to availability of fruits, and vegetables.

3. Wildlife trafficking and hunting: Some of the animal species have been included in the list of endangered species due to their use for commercial selling of horns, hives and other valuables.
